Skywall Translucent Systems of Terrell, Texas, has announced
the availability of SmoothSeal details for skylight sills and
purlins. SmoothSeal is designed for use on Advanced Translucent
Skylights where the rafter bay spacing is 5-feet or less
on center, and the slope is 30 degrees or less.
According to the company, SmoothSeal, which features a special
backer rod along with a silicone sealant, is an effective weather
seal, and because there is no purlin cap, water does not pond
above the cap.
